Drill Rod Tool Steels 86220258 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 86220258 is an A2 air-hardening tool steel flat stock bar used in precision toolmaking, die work, and machining applications. It measures 5/16 inch thick by 2-1/2 inches wide by 18 inches long and is manufactured to tight dimensional tolerances: plus or minus 0.001 inch on thickness, plus 0.000 to minus 0.005 inch on width, and plus or minus 0.062 inch on length. AISI A2 tool steel offers good wear resistance and dimensional stability through the air-hardening process, making it a reliable choice for blanks, punches, forming dies, and fixture components.

This flat stock is suited for machine shops, tool and die operations, and maintenance departments where precision steel stock is cut to size and heat treated on-site. The 18-inch bar length provides enough material for most small-to-medium tool blanks without requiring additional sawing from longer stock. It is used across general manufacturing and industrial maintenance environments where A2 grade tool steel is specified. The bar arrives in an annealed or pre-hardened condition typical for A2 flat stock, ready for machining before final heat treatment.

Key Features

• AISI A2 air-hardening tool steel for good wear resistance and dimensional stability after hardening
• Tight thickness tolerance of plus or minus 0.001 inch for precision fitment in die and tooling applications
• Width tolerance held to plus 0.000 to minus 0.005 inch for close-clearance work
• Square tolerance of plus or minus 0.003 inch ensures accurate cross-section geometry
• 18-inch bar length suits typical tool blank and die component applications
• Single-piece minimum order quantity allows purchase of individual bars without bulk commitment

Compatibility

Designed as a standard AISI A2 tool steel flat bar compatible with conventional air-hardening heat treatment processes used in tool and die, punch press, and precision machining applications.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified tool and die makers or machinists familiar with high-carbon alloy steels. Always wear appropriate PPE when cutting, grinding, or handling steel stock with sharp edges. A2 steel is air-hardened and should be heat treated according to the applicable metallurgical specification to achieve desired hardness. Consult the material data sheet for recommended hardening temperature ranges before processing.
